These days experience, like many other things, is becoming increasingly expensive. One's got a lot to get an experience, even 　41　 　one.

Not long ago, I wanted to 　42 　　my friend to a lunch. What we really needed was a good and quiet place for some conversation, not a big meal, so I selected one only for people including myself who 　43　 　to a particular club. What could be nicer? "Let's go to the 　44 　," I told my friend.

When I ordered a day in advance, I was asked 　45　 　I would eat a 20 yuan 　46　 　a 50 yuan lunch. I said, "50 yuan". I didn't 　47　 　, until I was asked to pay 　48　 　the lunch, that "50 yuan" means "50 yuan for each person."

　There were five of us the other day, and all of us were surprised by the quality of the 50 yuan meal (for 　49 　, we thought). The bill came at last; it was 310. 40 ( 　50　 　yuan for the five of us plus the charges for 　51　 , fruits and air-conditioning). I paid the bill without a 　52　 .

What could I say? It was not 　53 　　fault. It was my own 　54　 　that made me pay the largest lunch bill of my life.

On the whole, it was not so unhappy, we had a good lunch and in a beautiful place. 　55　 , the experience was valuable, and will 　56　 　in later years.

To support the logic(逻辑) of the lunch　 57　 , I have developed my own way to explain it: 50 yuan for the　 58 　and 260.40 for the　 59　 .

This 　60　 　experience has made me ten times wiser.
